how safe is a deflux spray like this:
I've been using this for a few months now and it works great. but I worry about which components might have problems - such as trimmer pots, transistors on heatsinks (thermal gray pads), electro caps and even onboard relays.
my guess is that I should assemble all the parts that would be fully and completely sealed and then deflux. after that, use a 'no clean' solder when attaching the final parts (relays, pots, trimmers).
what do people do? it would be nice to just finish the whole board, do a light spray on the top and a heavier spray on the bottom and brush it (or canned-air dry it) but I do worry about the chemical getting into the electro caps and especially the multiturn cermet trimmers.
